Charge / discharge current detection circuit
The Charge/Discharge current detection circuit is shown in figure 6. This circuit is composed of
offset voltage adjustment circuit, buffer amplifier and resistor network.
The pre-amplifier amplifies the voltage of sense resistance to the voltage based on GND. The
voltage gain can be selected by microcomputer commands.
Buffer amplifier does an impedance translation between input and output.

Figure 6. Charge / discharge current detection circuit
The offset voltage can be compensated by adjustment circuit.
The function in detecting discharge current is shown in figure 7. The differential voltage of sense
resistor is input to +(plus) terminal of AMP 1 when discharge current is flowing in sense resistor.
Selecting high voltage gain by microcomputer’s command is capable of monitoring very little
discharge current accurately.
The differential voltage of sense resistor is input to -(minus) terminal of AMP 2 when charge current
is flowing in sense resistor. The methods of detecting in charging are the same as in discharging
except that AMP2 reverses input voltage before outputting.
